This is a port of MicroPython to the Calliope mini which uses the CODAL as the underlying target platform.

After cloning this repository update the submodules:

$ git submodule update --init

Then build the MicroPython cross-compiler:

$ make -C lib/micropython/mpy-cross

Note: you may need to add to the line above PYTHON=python (or some variant thereof) to select your Python executable (this defaults to python3); for example:

$ make -C lib/micropython/mpy-cross PYTHON=python

After setting up, go to the src/ directory and build (as above, you may need to add PYTHON=python to the make command):

$ cd src
$ make

That will build both libmicropython.a (from source in src/codal_port/) and the CODAL app (from source in src/codal_app/). The resulting firmware will be MINI.hex in the src/ directory which can be copied to the Calliope mini.

Once the firmware is on the device there will appear a REPL prompt on the serial port. To test it you can run:

>>> display.show(Image.HAPPY)
>>> audio.play(Sound.HAPPY)
